Oxygen-enriched environments significantly increase fire risk and raise the potential for oxygen toxicity in patients. Strict NFPA standards limit allowable chamber oxygen levels. Oxygen delivery systems must be carefully managed and monitored to balance therapeutic benefit with safety. CO₂ buildup is unrelated to oxygen concentration and is controlled by ventilation and scrubbers.

Clear labeling and color-coding of gas piping prevents dangerous mix-ups (e.g., connecting air to oxygen outlets). NFPA and OSHA require this as a safety standard.

A backup oxygen system ensures patient safety during prolonged treatments. Interruption of oxygen supply could compromise therapy or patient survival in emergencies like CO poisoning or embolism.

Rapid ascent does not allow adequate time for dissolved nitrogen to leave the tissues safely, leading to decompression sickness (DCS). Symptoms include joint pain, rash, dizziness, or paralysis depending on severity. HBO treatment following Navy decompression tables is the standard management.

The immediate action is to change chamber gas to air, reducing CNS oxygen toxicity. Seizures usually stop once oxygen exposure is reduced. Decompression is not the first step unless safety is compromised.
